“…However, if a correct description of plasma interaction with the first wall is required, then the grid should be extended towards the wall and the convenient equivalent rectangularity of the grid is lost. This approach is being developed (Bufferand et al 2011;Dekeyser et al 2011;Klingshirn, Coster & Bonnin 2013) but the codes featuring this refinement are not routinely available yet.…”

The basic physics of the processes playing the most important role in divertor plasma detachment is reviewed. The models used in the two-dimensional edge plasma transport codes that are widely used to address different issues of the edge plasma physics and to simulate the experimental data, as well as the numerical schemes and convergence issues, are described. The processes leading to ultimate divertor plasma detachment, the transition to and the stability of the detached regime, as well as the impact of the magnetic configuration and divertor geometry on detachment, are considered. A consistent, integral physical picture of ultimate detachment of a tokamak divertor plasma is developed.

“…Previous work in this direction has already been performed using the SOLPS4 [20,21] and SOLPS5.0 [22] code bases. In the current version of SOLPS-ITER, discretization up to the real vacuum vessel wall is only performed for the calculation of neutral trajectories within Eirene, using an unstructured triangular grid.…”

“…In the current version of SOLPS-ITER, discretization up to the real vacuum vessel wall is only performed for the calculation of neutral trajectories within Eirene, using an unstructured triangular grid. What is now needed is to apply the experience gained in the previous extensions [20][21][22] and transpose them to the SOLPS-ITER code base. This work will of course need to be validated via strict benchmarks, following the procedure established in [21].…”

We present in this paper the code package SOLPS-ITER, initially introduced by S. Wiesen et al. [J. Nucl. Mater. 463, 480 (2015)], dedicated to simulations of plasmas in the edge region of fusion devices. This package brings together previously existing SOLPS implementations and aims to become the new standard SOLPS version. We summarize the benchmarking work done to ensure backward compatibility with previous work, with a strong requirement on maintaining the viability and usability of the already extensive database of SOLPS runs used for the ITER divertor design and edge plasma physics studies worldwide over the years. The SOLPS-ITER package includes not only the plasma (B2.5) and neutral (Eirene) transport solvers, but also a large set of software tools for input file build-up, conversion of old runs, inline run analysis, and post-processing, all within a standardized portable run environment and version control system. Ongoing and planned upgrades to the code, such as extending the computational domain to the full vacuum vessel wall and a new graphical user interface, are also discussed.

“…Preliminary analysis has shown that this shortcomming leads most likely to an overestimation of both erosion and deposition, thus, the results of the present paper are conservative. A proper solution of this problem is beyond the scope of current work and is developed elsewhere, see [6] and [7].…”
